USGS Topo · Published 2010About this map
Lake J B Thomas dominates this West Texas landscape, where the Colorado River is impounded by the Lake J B Thomas Dam. This 2010 survey illustrates the hydrography of Howard County, tracing the finger-like reaches of the lake including the flooded valleys of Wildcat Creek and Sourdough Draw. The terrain is characterized by a network of ranch roads and remote landholdings, most notably the Conrad Ranch situated centrally between the lake and the southern creek beds.
